Over on competition diesel there is a guy named dieselfreak who talks a lot about compounds. Apparently one rough way to size them is to compare inlet diameters. The little one should be 0.707 x the big one, so the big one will have twice the cross sectional area of the little one. Doesn't help with turbine housing sizing, and street compounds are usually a bit less, and you should subtract the hub diameter, but I found it a useful guide.
I think that tdo4l19t is a pretty good replacement for the 617 turbo (is a good hp turbo for compounds). Dougal on 4btswaps has a thread on the 617 that is nice.
Cool about the tormach . I have a cheapo CNC router.
I am seriously considering the air water route, but I think whipplem104 got an a/a setup into a w124 with Ac, so might try it. Tired of blowing boost hoses off, so the Sultzi style intake is attractive also.
Good luck and please keep updating the thread!

So high egt's can be tolerated for the short durations of time while the pistons etc soak up the heat.
